Banner notifications

Is there a way I can programatically make notifications persistent (i.e have to be dismisssed by the user) either with no action needed from the user of from a workflow in the app that will enable me to ask or require the user to set notifications from my app to be persistent
Logically, the decision to make notification persistent is left as user decision

So, in your app, you could propose user to change its settings, explaining the added comfort he/she will get with persistent notifications.

Or, try to get the notifications in your app and let user see them from there, with getDeliveredNotifications

getDeliveredNotifications(completionHandler:)
    Returns a list of the app’s notifications that are still displayed in Notification Center. 

Declaration    
func getDeliveredNotifications(completionHandler: @escaping ([UNNotification]) -> Void)

Parameters    
completionHandler    
The block to execute with the results. This block may be executed on a background thread. The block has no return value and takes the following parameter: 

notifications    
An array of UNNotification objects representing the local and remote notifications of your app that have been delivered and are still visible in Notification Center. If none of your app’s notifications are visible in Notification Center, the array is empty.
